Pin Number Pin Name Description
Supply Voltage Input Pin. TD1583 operates from a 3.6V to 28V DC voltage.
Bypass Vin to GND with a suitably large capacitor to eliminate noise on the input.
Power Switch Output Pin. SW is the switch node that supplies power to the
Ground Pin. Care must be taken in layout. This pin should be placed outside of
the Schottky Diode to output capacitor ground path to prevent switching current
spikes from inducing voltage noise into TD1583.
Feedback Pin. Through an external resistor divider network, FB senses the
output voltage and regulates it. The feedback threshold voltage is 1.222V.
Enable Pin. EN is a digital input that turns the regulator on or off .Drive EN pin
high to turn on the regulator, drive it low to turn it off.
